You have several good, legal options to listen to audiobooks for free, each with different strengths and limitations.

Library-powered apps (best starting point)

These feel the most like “Netflix for audiobooks” once you’re set up with a free library card.

  • Libby (by OverDrive) – Connects to your local public library and lets you borrow thousands of audiobooks at no extra cost if you have a library card. You can place holds, adjust playback speed, and download for offline listening.
  • Hoopla – Similar to Libby but often offers instant-borrow titles with no holds; also includes comics, movies, and music. You just log in with a participating library card.
  • Other library services – Some libraries also mention Kanopy (more for video) and general ebook access alongside audiobooks.

These are a great “set and forget” route: once you have a card, nearly everything you listen to feels free.

Public domain classics (no card needed)

If you’re into classics or older works, public-domain platforms are completely open and legal.

  • LibriVox – Volunteer-read recordings of public-domain books such as classics and older non-fiction; thousands of titles, fully free.
  • Project Gutenberg – Primarily free ebooks, but also links to or hosts some public-domain audiobooks.
  • Digitalbook.io – Aggregates free audiobooks and ebooks from multiple public-domain sources into one place, accessible via web or a mobile app.

These are ideal if you’re happy with older literature and don’t mind variable narrator quality.

Big platforms with free sections

Some major audiobook/streaming brands now maintain always-free catalogs or partially free access.

  • Audible (free listens section) – Has a dedicated page where you can stream hundreds of audiobooks and podcasts without a paid membership, just by signing in with an Amazon account.
  • AudioReads – An online library offering free English audiobooks to stream with no subscription.
  • Digitalbook.io – Besides being an aggregator of public-domain titles, it markets itself as a source of free audiobooks without subscription, using popular formats and online streaming.

These can be a good way to get polished, professionally produced content without committing money upfront.

Music & video platforms with full books

People increasingly treat these as “stealth” audiobook apps.

  • Spotify – Hosts a growing number of full-length audiobooks, including public-domain works and curated playlists under audiobook-focused accounts; some listeners report finding popular non-fiction there as regular tracks or playlists.
  • YouTube – Many channels upload full audiobooks (often classics or older titles) and curated “audiobook” playlists; some creators specialize in public-domain recordings.

Quality and legality can vary on user-uploaded content, so it’s best to favor established channels that clearly specialize in audiobooks.

Free trials and promos (short-term “free”)

These aren’t permanently free, but they can give you several full books at no cost if you keep track of cancellations.

  • Audible free trial – Typically offers a 30-day trial with one or more audiobook credits you keep even if you cancel before billing.
  • Audiobooks.com – Often promotes a free month or discounted multi‑month intro deals that include several titles.
  • Deals-oriented apps – Services like Chirp and Libro.fm focus on heavily discounted audiobooks; while not always free, they often complement your free-listening strategy with very cheap purchases.

If you stagger trials across services, you can realistically listen to quite a few premium titles free over a few months.

Tiny “listener story” for context

Imagine you get a new library card this week and install Libby. You queue up a couple of popular fantasy novels and a memoir, but they have waits, so you also grab a few LibriVox classics and stream a free title from Audible’s free list while you wait. In a single month, you’ve listened to five or six full books without paying a cent, just by hopping between library apps, public‑domain sources, and the free catalogs on big platforms.

TL;DR:
Your best bet is to combine a library app (Libby or Hoopla), a public‑domain source (LibriVox, Project Gutenberg, Digitalbook.io), and at least one big- platform free section (Audible free listens, Spotify/YouTube, AudioReads) so you always have something free and legal to listen to.
